I frequently find myself sorting the good from the bad batteries with my digital multimeter. This usually has me doing the Mr. Miyagi rolling-battery-chopsticks-challenge.

If you have a magnetic parts tray near by, stand up those batteries, use an alligator clip to attach a ground to the edge and you can test your batteries one handed!

This should work for most battery styles (even coin-style). Just be careful not to short anything out!

Happy testing!

<p>Will use this to modify my third hand: Third Hand for Your Multimeter</p><p><a href="https://www.instructables.com/id/Third-Hand-for-Your-Multimeter/" rel="nofollow">https://www.instructables.com/id/Third-Hand-for-You...</a></p><p>Nice job.</p>
I'm kind of ashamed to admit this but I read the link in hackady and was immediately confused as to how this would ever work, but then realised you're not using PP3s, it is a stroke of genius.
<p>WHAT A GENIUS! :)</p>
